IRVINE, Calif. — Dahua Technology is introducing a new line of expandable 2-wire IP video intercom solutions for the North America market.

“Most 2-wire intercom systems only support audio, so adding video solutions often requires expensive, time-consuming rewiring,” says Damon Chou, solutions product manager for Dahua USA. “Dahua 2-wire IP video intercom solutions eliminate this barrier, making it possible to increase security with video and added functionality using existing wiring.”

Designed for multitenant commercial and residential buildings, as well as educational and medical facilities, the company’s 2-wire IP video intercom system allows tenants, property managers and owners to manage keyless entry and visually communicate in real time with visitors.

Each outdoor station includes a 2-megapixel camera with up to 1080p resolution, seamless IR operation with a wide vertical and horizontal field of view. The non-polarized 2-wire cabling system with new bus-based cascading technology is said to greatly improve cable utilization rate, reducing power supply wiring.

Because it can be installed using existing wiring, the 2-wire intercom solution also offers flexibility and cost-effectiveness. This allows users to deploy the system to support multiple communication paths and technologies without rewiring their location, making it ideal for both new installations and upgrades of existing systems.

This new system also supports standard Ethernet for flexibility if 2-wire is not available. These intercom solutions are said to be highly customizable based on project requirements, with options such as dial buttons, fingerprint reader, Mifare card reader, LED indicators and more to ensure the system meets end users’ specific needs.

Scalability is another hallmark of the new 2-wire video intercom solutions, according to the company. Users can start small with a single station and easily add outdoor stations and indoor monitors as their needs change, allowing their system to scale along with their businesses.

Dahua intercom devices are compatible with the SIP 2.0 protocol for Internet conferencing, telephony, event notification and instant messaging. SIP is widely used to initiate and terminate Voice over Internet Protocol (VoIP) calls, as well as connect physical devices to mobile applications, creating strong third-party integration capabilities.
